Conversions

(module
  (func (export "mix") (param $i i32) (param $f f32) (result f64)
    (f64.add
      (f64.convert_i32_s (local.get $i))
      (f64.promote_f32 (local.get $f))))
)

Conversion families:

• Int width: i64.extend_i32_s, i64.extend_i32_u, i32.wrap_i64
• Float width: f64.promote_f32, f32.demote_f64
• Float → int: i32.trunc_f32_s/u, i32.trunc_f64_s/u, i64.trunc_f32_s/u, i64.trunc_f64_s/u
• Int → float: f32.convert_i32_s/u, f32.convert_i64_s/u, f64.convert_i32_s/u, f64.convert_i64_s/u

See also Non-trapping float-to-int for saturating variants.
